Autor: Sadowski, W., Sayyari, M., di Mare, F., Marschall, H.

Publikováno v: Physics of Fluids 1 May 2023; 35 (5): 055121

The continuum approach employing porous media models is a robust and efficient solution method in the area of the simulation of fixed-bed reactors. This paper applies the double-averaging methodology to refine the continuum approach, opening a way to

Numerical verification of regularity in the three-dimensional Navier-Stokes equations

Autor: Robinson, J C, Sadowski, W

Publikováno v: Asymptotic Analysis 59 (2008) 39-50

Current theoretical results for the three-dimensional Navier--Stokes equations only guarantee that solutions remain regular for all time when the initial enstrophy ($\|Du_0\|^2:=\int|{\rm curl} u_0|^2$) is sufficiently small, $\|Du_0\|^2\le\chi_0$. I

Small and large polarons in nickelates, manganites, and cuprates

Autor: Calvani, P., Dore, P., Lupi, S., Paolone, A., Maselli, P., Giura, P., Ruzicka, B., Cheong, S-W., Sadowski, W.

By comparing the optical conductivities of La_{1.67}Sr_{0.33}NiO_{4} (LSNO), Sr_{1.5}La_{0.5}MnO_4 (SLMO), Nd_2CuO_{4-y} (NCO), and Nd_{1.96}Ce_{0.04}CuO_{4} (NCCO), we have identified a peculiar behavior of polarons in this cuprate family. While in
